Abstract: A data processing estimating method for privacy protection using a statistical estimation block design and a system for performing the method is disclosed. A data processing estimating system for privacy protection includes a block design unit for designing block designs for statistical estimation shared between data providers and data users; a modification data generating unit for generating modification data in a random manner along a conditional distribution for the original data of the above statistical estimation block design; and a data distribution estimating unit for estimating the distribution of the original data using an estimation function based on the statistical estimation block design. Accordingly, data processing techniques and estimation functions are provided by utilizing statistical estimation block designs shared between data providers and data users, thereby preventing leakages of sensitive personal information such as personal photos, purchase records, and locations included in the collected data, it is possible to increase statistical accuracy and communication efficiency while satisfying the goal of privacy protection by preventing leakage of sensitive personal information.
